Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a thresher having a Glen tank, and more particularly to a reinforcing structure for a lifting cylinder.

<Prior Art> Conventionally, a working tank having a threshing mechanism such as a combine is equipped with a Glen tank for storing threshed paddy. The paddy threshed by the threshing machine is sorted, conveyed by the lifting cylinder to the upper portion of the Glen tank, and stored in the Glen tank. The paddy stored in the Glen tank is conveyed upward by the lifting cylinder and transferred to a transportation vehicle such as a truck by the paddy discharge cylinder.

The lifting cylinder described above is generally fixedly supported by the Glen tank.

<Problems to be solved by the invention> However, the lifting tube has the base end of the paddy discharge tube attached to the upper end so as to be upright and horizontally rotatable, and moreover, a large amount of paddy is stored inside when the paddy is discharged. Therefore, special reliable and strong fixed support is required, but there is a problem that the frame support on the threshing machine side has a weak support strength and the rotation operation of the paddy discharge tube becomes unstable. Furthermore, the paddy discharge tube vibrates during the paddy discharge work, which causes problems such as noise generation and strength problems.

In addition, in the case of the structure in which the Glen tank is rotated, it is necessary to remove the attachment parts of the lifting cylinder and the lifting cylinder, which has a drawback that it takes time to remove the rotation system of the Glen tank.

<Means for Solving the Problems> The present invention for solving the above problems is to mount a grain tank 11 for accommodating threshed paddy on the body 1 side,
A structure in which a grain-lifting cylinder 15 that lifts threshed paddy and feeds it into the Glen tank 11 from above and a lifting barrel 19 that lifts and discharges the paddy in the Glen tank 11 are fixedly installed on the machine body 1 side. In the above, the lifting cylinder 19 is provided with a reinforcing member 34 whose one end is connected to the upper part of the lifting cylinder 19, and the other end of the reinforcing member 34 is connected to an upper position of the lifting cylinder 15. I am trying.

<Operation> The reinforcing member 34 reinforces the fried food cylinder 15 and the fried food cylinder 19 to prevent a load and vibration in the bending direction, and stabilizes the support and rotation operation of the paddy discharge cylinder at the upper end of the fried food cylinder 19. , The lifting cylinder 15 and the lifting cylinder 19 by connecting the respective upper positions of the lifting cylinder 15 and the lifting cylinder 19.
Mutually improve the strength of 19.

A discharge case 17 is attached to the upper end of the fried cylinder 15 and the discharge case 17
A discharge port 17a is formed on the Glen tank 11 side of
The discharge port 17a is connected to a paddy inlet 11a provided above the side surface of the Glen tank 11 on the airframe side.

On the rear right side of the Glen tank 11, a lifting cylinder 19 whose lower end is connected to the horizontal spiral is erected. The upper end of the lifting cylinder 19 projects to the upper side of the Glen tank 11, and a rotating gear case 21 is mounted thereon, and a paddy discharge cylinder 23 is connected to the rotating gear case 21 in the front-rear direction.

FIG. 3 shows a support structure for the lifting cylinder 19. A holding plate 25 bent in a V shape is welded in the middle of the lifting cylinder 19 so as to hold the lifting cylinder 19. The holding plate 25 is fastened with a connector 27,
The connector 27 is fastened to a plate 29 and connected to a support rod 31. The support rod 31 is inserted through and supported by the threshing machine frame 5a. With such a support structure, the lifting cylinder 19 is supported on the side of the machine body 1 and does not hinder the rotation of the Glen tank 11.

The upper ends of the lifting cylinder 19 and the lifting cylinder 15 described above are fixedly connected by a reinforcing member 34. The connection structure will be described below. At both ends of the reinforcing member 34, mounting plates 34a and 34b for fixing to the upper ends of the fried food cylinder 15 and the fried food cylinder 19 are attached. The mounting plate 34a at one end is the lifting cylinder 1
